Blue Rubicon is charged with raising awareness of the EC Harris corporate brand, enhancing understanding of its service offering and reinforcing its position as a market leader.

The agency will aim to showcase the consultancy's capabilities through a thought leadership campaign that focuses on key sectors such as energy and infrastructure. As well as supporting the UK business, the remit covers Asia and the Middle East.

Last year, EC Harris merged with Arcadis, giving it access to the latter group's network of 21,000 professionals across 70 countries.

"Effective communications are absolutely crucial to realising our continued growth ambitions, so that we can boost our penetration in key sectors," said Andy Rowlands, group PR manager at EC Harris.
